BGH97M080B3A-Bosch 97% Gas Furnace 80,000 BTUH, B Cab R454

Bosch BGH96M080C4C is a 96% AFUE condensing gas furnace for contractors specifying high‑efficiency residential and light‑commercial installs, featuring a two‑stage gas valve and multipoise cabinet for easy retrofit or new‑build applications. (bosch-homecomfort.com) It integrates with Bosch IDS heat‑pump systems for dual‑fuel operation, supports low‑GWP R‑454B pairing, and is covered by Bosch’s 5‑year parts and 20‑year heat‑exchanger limited warranty. (bosch-homecomfort.com) I used Bosch BGH96 product pages and the IDS service manual to prepare this description; the exact model/part number (8733965435) was not listed on Bosch North America pages, so the copy is based on verified series‑level details.
